I am currently in the same situation. Cycle day 13, and 4 positive ovulation tests. When I asked my doctor about this, he said I was getting "false positives," because I tested too early. I was not supposed to test until day 11, but since day 11, I have had two positives. So I don't know if I ovulated or not.... I am on clomid, are you?
Good luck to you!
